From db829b4150b6c5a8e81d80bfa2a446a92627ce42 Mon Sep 17 00:00:00 2001 From: Matteo Croce Date: Mon, 11 May 2020 13:32:34 +0200 Subject: [PATCH] samples: bpf: Fix build error [ Upstream commit 23ad04669f81f958e9a4121b0266228d2eb3c357 ] GCC 10 is very strict about symbol clash, and lwt_len_hist_user contains a symbol which clashes with libbpf: /usr/bin/ld: samples/bpf/lwt_len_hist_user.o:(.bss+0x0): multiple definition of `bpf_log_buf'; samples/bpf/bpf_load.o:(.bss+0x8c0): first defined here collect2: error: ld returned 1 exit status bpf_log_buf here seems to be a leftover, so removing it.
